We have purified the human T-cell growth factor (interleukin-2) receptor and have cloned, sequenced and expressed cDNAs corresponding to this receptor. We identify one gene, but two interleukin-2 receptor mRNAs which differ in their polyadenylation signals. We have isolated an additional cDNA that may correspond to an alternatively spliced mRNA that lacks a 216 base segment and appears to encode an altered membrane protein which cannot bind interleukin-2.
我们已经纯化了人T细胞生长因子（白细胞介素-2）受体，并克隆、测序并表达了与该受体对应的cDNA。我们鉴定出一个基因，但有两种白细胞介素-2受体mRNA，它们的聚腺苷酸化信号不同。我们还分离出了另一种cDNA，它可能对应于一种选择性剪接的mRNA，该mRNA缺少一个216个碱基的片段，似乎编码一种不能结合白细胞介素-2的改变的膜蛋白。
